What it is

The Heatline D003202395 is a 3 bar pressure relief valve used in Heatline Capriz Plus and Monza gas boilers. It sits on the heating circuit and opens at its set pressure to discharge excess water, protecting the boiler, seals and system components from over-pressurisation. It is a direct replacement for the valve originally fitted to these appliance families.

Signs this part needs replacing

  • Water weeping or dripping from the discharge pipe while the system is cold
  • System pressure dropping repeatedly and needing regular topping up
  • Pressure gauge climbing above the normal cold fill reading
  • Scale, debris or staining visible around the valve outlet
  • Valve failing to reseat and continuing to pass water after a discharge

Before you order

  • Check the GC number on the appliance data badge against the list above to confirm the valve suits your model.
  • Confirm the rating required — this is a 3 bar unit.
  • Inspect the sealing washer or O-ring at the valve connection and renew it if it is compressed or perished.
